Serial No. 462,604.

This invention relates to new and useful improvements in the general art of ventilators and more particularly to a device of this character which is adapted to be mounted in the foundation wall of a house or other building beneath which there is no basement or cellar.

An important object of the invention is to provide, in a manner as hereinafter set forth a. ventilator of the afor'ementioned character having means associated therewith whereby the ventilator may be expeditiously closed when it is so desired, as in cold weather and the invention further includes novel means for storing the closure when the same is not in use.

Another* important object of the invention is to provide a ventilator of the character described embodying a novel construction and arrangement of parts whereby the passage of rodents, insects, etc., will be prevented at all times.

Other objects of the invention are to provide a ventilator of the character set forth which will be comparativel'y simple in construction, strong, durable, efficient in its use and which may be manufactured at a low cost.

All of the foregoing and still further objects and advantages of the invention may become apparent from a study of the following specification, taken in connection with the' accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:-

Figure 1 is a view in front elevation showing a ventilator constructed in accordance with this invention mounted in position in a wall.

Figure 2 is a view in vertical cross section thereof.

Figure 3 is a view in elevation looking at the device from the interior of the wall and showing a corner portion of the shiftable screen frame which is mounted on the ventilator casing.

Figure 4 is a fragmentary detail view in cross section and on an enlarged scale showing the means of slidably mounting the closure plate and taken substantially on the line 4-4 of Figure 2.

Figure 5 is a fragmentary detail view in perspective showing one of the lower corner portions of the slidable screen frame.

Referring to the drawings in detail, it will be seen that the reference numeral 1 designates a substantially rectangular metallic casing which is adapted to bemounted in an opening provided therefor in the wall 2. A grid 3 is mounted on the outer side of the casing 1 and while saidgrid is shown as being formed integrally with a casing in the drawings, it is to be understood that the same may be formed of a separate piece of material and detachably secured by any suitable means to the casing. In its upper marginal portion the grid 3 is formed to provide a transversely eXtending slot 4 and Said grid is further formed 'to provide, in its* lower marginal portion, a transversely eXtending slot 5.

Formed integrallyon the opposite end walls of the casing 1 are the pair of diago nally extending channel forming ribs 6 which slidably and removably support the metallic closure plate 7 in the casing 1. The upper ends of the channels formed by the ribs 6 communicate with the opposite ends of the slot 4 and said plate 7 is inserted in the chan- 'nel through said slot. The upper end of the closureplate 7 projects through the slot 4 when said plate is mounted in operative position in the casing 1 an d terminates in a rolled portion 8 which provides means for obtain ing a grip on said closure plate for facilitating the insertion or removal thereof.

Mounted on the inner side of the casing 1 'is a substantially rectangular frame 9 in which is secured in any suitable manner the scr-een 10. The frame 9 is mounted for vertical sliding movement on the casing 1 through the medium of the slots 11 through which the securing screws 12 extend. On its lower end portion and on the inner side thereof, the frame 9 has mounted thereon the inwardly projecting horns or Cams 13.

In use, the casing is mounted in the wall in the manner clearly illustrated in the drawings, and when it is desired to close the Venn sure plate is moved rearwardly or inwardly across the lower wall of the casing l and when the inner edge thereof engages with the-horns or cams 13, the frame 9' and screen 10 will be moved upwardly on the Screws 12 in' a manner to permit said closure plate to slide therebeneath. lVhen the closure plate is withdrawn from this position, the frame 9 and the screen -10 will gravitate for closed position. The screen 10 will at all times prevent the passage of rodcnts, insects, etc., through the ventilator as will be readily .apparent.

It is believed that the many advantages of a ventilator constructed in accordance with this invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction may be had Which will fall Within the scope of the invention as claimed.

VVhat is claimed is 1. A ventilator of the character described comprising a casing open at its front and rear, a grid in the front portion of the casing, a screen mounted on the rear portion of the casing, and a closure plate removably mounted for diagonal sliding movement in the casing intermediate the grid and the screen. a

2. A ventilator of the character described comprising a casing open at its front and rear, a grid mounted on the front portion of the casing and having atransversely extending slot in its upper marginal portion, pairs ofdiagonally extending ribs on certain of the walls of the casing, said ribs forming channels communicating, at one end, with the opposite end of the slot in` the grid, a closure plate insertable through the slot and slidably mounted in the channel formed by the ribs.

3. A ventilator of the character described comprising a casing open at its front and rear, a grid mounted on the front portion of the casing and having a transversely eX- tending slot in its upper marginal portion, pairs of diagonally extending ribs on certain of the walls of the casing, said ribs forming channels communicating, at one end, with the opposite end of the slot in the grid, a closure plate insertable through the slot and slidably mounted in the channel formed by the ribs, and a screen mounted for vertical sliding movement on the rear portion of the casing.

4. A ventilator of the character described comprising a casing open at its front and rear, a grid in the front portion of the casing having transversely eXtendingslots in its upper and lower marginal portions, pairs of ribs on certain of the walls of the casing forming diagonally extending channels communicating, at one end, with the opposite ends of the upper transverse slot in the grid, a closure plate insertable through the upper slot of the grid forslidable disposition in the channel in a manner to closethe air passage through the casing when said plate is in its operative position, said plate being further adapted for insertion through the lowermost slot into the casing when in its inoperative position.

5. A ventilator of the character described comprising' a casing open at its front 'and rear, a grid in the front portion of the casing having transversely extending slots in its upper and lower marginal portions, pairs of ribs on certain of the walls of the casing forming diagonallyextending channels communicating, at one end, with the opposite ends of the upper transverse slot in the grid, a closure plate insertable through the upper slot of the grid for 'slidable disposition in the channel in a manner to close the air passage through the casing when said plate is in its operative position, said plate being further adapted for insertion through the lowermost slot into the casing when in its inoperative position, a screen mounted for vertical sliding movement on the rear portion of the cas- V ing, and inwardly projecting cams on the lower portion of the screen for engagement by the closure plate when saidclosure plate isinserted through the lower slot ina manner to elevate the screen for `permitting the passage of the closure plate. y
